TWISQLLING AND 1V INDING APPARATUS.

Application filed May 19, 1923, Serial No. 640,169. Renewed May 11, 1926.

This invention relates to twisting and winding apparatus'of that type comprising a yarn receiver and a winding head which are rotatable relative to each other and are arranged so that the winding head lays the yarn in the yarn receiver in loops forming layers extending transversely to the axis of rotation. An example of a winding machine of this general type is illustrated in my Patent No. 1,258,412, dated March 5th, 1918.

One feature of the present invention relates to means whereby the spacing of the loops in each layer can be varied so that the loops may be laid closer to or further from each other as desired.

Another feature of the invention relates to an improved means for supporting and operating the winding head by which the yarn is laid.

Still another feature of the invention relates to an improved manner of operating and controlling the cam which in turn controls the laying arm and compensating arm.

Still another feature of the invention relates to a novel means for controlling said cam by which the relative rotative movement between the cam and the housing and yarn container can be varied thereby varying the 30 spacing of the loops.

Still another feature of the invention relates to means whereby this relative spacing of the loops and the relative motion between the winding head and the yarn receiver by which the amount of twist put into the yarn is determined can be controlled from the end of the frame. 1

Other features of the invention relate to various improvements which will be more fully hereinafter set forth.

Fig. 10 is a section on the line 1010, Fig. 8; y i

Fig. 11 is a section on the line 11-11, Fig. 8. j l @In the drawings 1' indicates a rotatable yarn receiver preferably having'a cylindrical shape and in which the yarn mass 2 is laid up in loops forming layers extending transversely to the axis of rotation all as usual in winding and twisting machines of ing head is received, this housing being keyed to the shaft 3 as shown at 8. The

yarn receiver 1 will be supported on a suitable step bearing and it is connected to the iousing 7 so as to rotate therewith by means of one or more spring-pressed locking pins 9 carried by the housing and adapted to enter recesses 10 in the upperedge of the receiver all as shown in my co-pending application Serial No. 572,441, dated July3, 1922.

As stated above the shaft 3 is rotatable and for this purpose it has a gear 11 fast thereon which meshes with and is driven by a gear 12, the latter having rigid therewith a bevel gear 13 which meshes with and is driven by a bevel gear 14 on a shaft 15 extending longitudinally of the frame. This shaft 15 is the shaft to which power is applied and from which the machine is operated.

The winding head by which the yarn mass 2 is laid up is received within the housing? and it comprises the usual winding plate 16 which rests on the yarnmass and is formed with a radial slot 160 through which the yarn 161 is delivered to the yarn mass, such yarn being traversedin the slot by means of an oscillating yarn-laying arm 17 all as usual in machines of this type.

Associated with the yarn-laying arm 17 is a compensating arm 33 which also oscillates horizontally and which serves to maintain an even tension on the yarn. The yarn 161 passes from the bore 4: in the shaft 3 to the eye 162 at the end of the compensating arm and thence passes to the eye 163 in the end of the yarn-laying arm and from the latter is delivered to the slot 160 of the winding plate, all as usual in winding heads of this type. Said winding head also includes a cam for oscillating the yarn-laying arm and the compensating arm as will be presently described. This winding head is supported on the lower end of the shaft 3 and is rotatable thereabout.

The winding plate 16 ofthe winding head is secured to a head member 18 by means of suitable posts 19 andsaid head member is supported and rotatably mounteo on'the shaft 3, through the medium of ball bearin-gs'20. The head member is retained in place by means of a nut 21 which is screwthreaded to the lower end of the shaft 3, The'wind-ing, head including the head member 18 and Winding plate 16 is given a lo tative motion relative to the yarn receiver 1 ibymeans' of the following mechanism.

The head member 18 is provided with an internal- .gear 22 which meshes vith gears 23 formed on the lower end of studs 2 1 that are journal-ledin the bridge portion 25 of the housing 7, said studs 24 having fast on their upper ends gears '26 which mesh with a gear 27- loosely mounted on the shaft '3. This gearw27 is a long gear which projects through the cap plate :28 of the housing and Which meshes with and is driven by a. controllingsgear 29 whichin turn is driven from a shaft 30 that extends longitudinally of the machine through-suitable intermesh-ing gears 31, 32., the latter being rigid with the gear The'yarirlaying arm 17 and the compensating arm 33 are supportedby vertical rock shafts 3e, 35 which in turn are journalled in the head member 18 and these rock shafts are given their oscillating movement through a cam memberv 36, which is also supported by the shaft 3-and is rotatable thereabout.

The cam member by which the compensating. arm" 33 and yarn-laying arm 17 are oscillating is provided with a double oa'm groove comprising the two cam grooves 39 and 42 which are formed on the under face ofrthe cam member, one of said cam grooves controlling the yarn laying arm 17' and the other controlling the compensating arm 33,

Therock shaft 3% of the yarn-laying arm has at its'up-per end a crank pin 37 carrying a roll- 38 that ope-rates in the cam groove '39 and the rock shaft 35 for the compensat ing arm also has at its upper end a crank arm 10 carrying a roll i1 that operates in the cam groove 42, these grooves being so shaped as to give the yarn-laying the necessary oscillating movement to lay the yarn in the loops and to give the compensating arm the necessary oscillating movement to maintain the yarn under a substantial uni form tension.

The cam is given a rotation relative to the housing member as usual in machines of this type and for this purpose said cam has rigid therewith a gear 43 which meshes with gears it formed on studs e5 which are journalled in the bridge portion 25 of the housing, said studs having rigid therewith gears 46 which mesh with a gear 4:? supportedby and free to revolve on the, shaft- 3. This gear 47 is shown as having a hub portion tS extending through the gear 27, and onwhich it is rotatably mounted, said hub portion carrying at its upper end a gear 49 which meshes with and is driven by a gear 50., The,

gear 50 in turn is driven from a. shaft 51 that extends longitudinally of the machine and for this purpose the gear 50 has rigid therewith a worm or spiral gear 52 meshing with and driven by a complemental gear 53 fast on the shaft 51.

The structure herein shown is further provided with capstans, for drawing the yarn through the hollow shaft 3 and delivering it to the compensating arm and yarn-laying arm thus relieving the latter-of the work: of pulling the yarn into the machine. There are two such capstans indicated at 101 and 102, said capstans being situated belowthe head 18 and substantially in the plane of the lower end of the shaft3. These capstans are fast on shafts 103 and 10twhich are journalled in the lower portion of, the head and each shaft has fast thereto at its upper end a gear 105 which canbe driven either from the cainmember36 or from the shaft 3. In the construction shown said gear 105 is. driven from the cam member 36 and for this purpose the cam member has rigid there with a gear 106 with which'the gear 105 iii-- termes hes. The rotation of the winding head relative to the 02111136 or the housing? will thus rotate the capstans 101,102 and the latter will operate to draw the yarn positively through the bore a of the tube 3 and deliver it to the compensating arm. With this arrangement it will be noted that the capstans are located within the winding head and in close proximity to the compensating arm and yarnelaying arm.

lVhen a machine of this type is in operation the yarn container 1 with the yarn therein is rapidly rotating at one speed and the windinghead 18-within the housing 7 is rotating at a different speed while the cam 36 is rotating at a speed different from that of either the housing or the winding head. The yarn, therefore, will be drawn into and laid on the yarn mass because of the fact that the winding head with its winding plate 16 is rotating at a different rate of speed from that of the yarn receiver and the oscillating mot-ion of the yarn-laying arm 17 will cause the yarn to be laid in loops extending transversely to the axis of rotation, sald loops being lald progressively so as to form layers.

The amount of twist which is put into the yarn depends upon the relation between the speed of rotation of the yarn receiver 1 and the rate at which the yarn is wound; and the rate at which the yarn is wound is determined by the relation between the rotation of the yarn receiver and that of the winding head. This relation is determined by the relative speed of rotation of the shafts 15 and .30 so that by varying the relative speed with which these shafts rotate the amount of twist and the speed which which the yarn is laid can be determined.

The spacing of the individual loops of each layer is determined by the relative speeds of rotation of the cam 36 and the yarn mass, (the latter having the same speed of rotation as the housing and yarn container) and this in turn is determined by the relation between the speed of rotation of the shafts 15 and 51. If the difference between the speed of rotation 'of the cam 36 and the yarn is increased then the loops will be laid an increased distance apart and if this difference is diminished then the loops will be laid nearer together.

While the above description relates to a winding and twisting unit comprising a yarn receiver and its winding head yet it will be obvious that any number of such winding and twisting units may be supported on the same frame in which case each one may be geared to the shafts 15, 51 and 30 so that said shafts will control all of the individual units. 7 7

One arrangement by which the shafts 15, 51 and 30 can be utilized to operate a number of winding and'twisting units is shown in Fig. 3, wherein a set of four winding and twisting units are grouped about each set of gears 1:2, 50 and 29 and wherein the shafts 15, 51 and 30 are arranged to operate a plurality of ets of gears 12, 50 and 29. The number of sets of such gears will depend entirely upon the length of the frame.

lVhere this arrangement is employed all the winding-units of the several groups will operate alike and the same amount of twist will beput in the yarn which is delivered to all of the winding units, and the spacing of the loops in all the yarn receivers can be varied simultaneously by merely varying the relative speeds of the shafts 15, 80 and 51 as above described. 5

I have provided herein means situated at the end of the frame 5 by which the relative speeds of these shafts can be varied thereby to secure variations in the degree of twist put into the yarn and also to secure variations in the spacing of the loops as they are laid. This'controlling mechanism is illustrated in Figs. 3, 8, 9, 10 and 11,

and it comprises a system of gearing placed in a gear box at the end-of the frame and connecting the shafts 15, 30 and 51, which in many respects is similar to the gearing in the winding head.

It will be remembered that the shaft 15 is the shaft which has the power applied thereto so that said shaft constitutes the prime mover for the moving parts of the machine. This shaft 15 is rotating at a constant speed. I It will also be remembered that said shaft 15 runs the length of the frame and drives the housings of the various units. This driving shaft 15 is operatively connected at one end of the frame to a gear 79 which is situated in the gear box at the end of the frame (see Figs. 8 and 11), the connection between the shaft 15 and the gear 79 being such as to cause said gear 79 to rotate synchronously -with the shaft 15. This gear connection comprises a gear 55 fast on the shaft 15 and meshing with a gear 58 which is fast on a sleeve 63 journalled in the end of the frame. The gear 58 in turn meshes with a gear 81 which is fast on a shaft 80 journalied in the end of the frame, said shaft 80 having the gear 7 9 fast thereon. Thetrain of gears connecting the shaft 15 to the gear 79 thus comprises the gears 55, 58, 81 and shaft 80 and the gear 79 rotates synchronously with the shaft 15.

A. change gear connection is interposed between the' 'ear 79 and the shaft 30 by which the relative speed of the shaft 30 and the gear 79 may be varied and since the gear 79 rotates synchronously with the shaft 15 this change gear device provides means for varying the speed of the twist regulator shaft 30 relative to the main driving shaft The twist regulator shaft 30 which also extends the lengthof the frame has a gear 74 rigid therewith which meshes with a gear 75 mounted on a stud 76 which is adjust ably mounted in brackets 77. The st'hd 7 6 also has a gear 78 thereon which meshes with the gear T9. The bracket- 77 is provided with a slot 82 in which the stud 76 is justed and the gear 7 8 is removably mounted on the stud. With this construction the gear 78 may be removed and replaced by a larger or smaller gear which may be brought into mesh with the gear 79 by proper adjustment of the stud 76. This provides a change gear construction by. which the relative speed between the gears 74 and 79 can be varied thereby varying the relative speed between the driving shaft 15 and the twist regulator shaft 30. thus changing the speed of the shaft 30 relative to the driving shaft 15 a corresponding change is effected in the amount of twist which is put into the yarn.

The regulation of the spacing of the loops is secured by varying the speeed of the shaft 51 relative to the shafts 15, 30 and l iis sleeve or hollow sh ft .63 has fast thereto at its end a which forms one of a pair of loop-regulating gears, this gear 6% being driven directly from the driving shaft 15 at a speed of unvarying ratio with that of the driving shaft.

The other gear of the pair of loop-regulating gears is the gear 62 which has the pitch diameter as the gear 6% and is located coa:;ially therewith, said gear 62 being mounted on shaft 61 which extends through the hollow shaft This shaft 61 thereto a car which meshes with a gear 57 on the loop-regulating shaft 51. y

The gears 62 and 6-l are connected through a hunting gear 65 which meshes with both gears d is rotatably mounted on a stud 66 that is adjustably carried in a plate 67 formed on a sleeve 68 that is journalled in the frame. The rotation of the gears 62 and 64.- is differentiated primarily by having a different number of teeth in said gears so that at each revolution thereof one of the gears will gain or lose slightly with erence to the other gear, and secondarily by providing means for rotating the plate 67 through the joint action of the shafts 15 and 30.

The sleeve 68 has rigid therewith an internal 69 which meshes with and is driven by a pinion 7 0 on a shaft 71 carried by the gear 58, which it will be remembered meshes with the 55 fast on the main drive shaft 15. The shaft 71 also carries a gear 72 which meshes with a gear 73 rigid with a gear 59 that in turn meshes with a gear 56 rigid with the twist-regulating shaft 30. The ratio of the gearing 7 3, 72, 70, 69 must be the same as the ratio in each winding and a .visting unit between the gears 27, 26, 23, 22. This being so no matter what change is made in the change gears 7 5 and 7 8 the ratio in the gear box at the end of the frame between the gears 64- and 67 will be the same as the ratio between the shaft 3 of each individual winding and twisting unit and its winding head 18 and the number of loops which are laid in each layer will be represented by the ratio between the number of teeth in the 62 and 6%, corsimilar gears used in the mg heads and described. in above-mentioned patent. The hunting 65 has been des ribed as adjustably mounted on the plate 67. This is to provide for changing the gears 62 and 64 so as tile supported in the plate 67 in any appropriate way. As herein shown said plate is formed with slotted ears 92 in the slots 91 which the studs are adjustably mounted.
